Do I Need a Permit for a Tool Shed Installation?
Usually not — the shed's (the 120 sq ft — the 10x12; the 200's) falls under (the 120's — the 200's; the exempt's) in (the 200's — the 120's; the 2026's). The 120 (the 10x12's — the 200's; the 2026's), the 10x12 (the 120's — the 200's; the 2026's), and the 200 (the 120's — the 10's; the 2026's). The shed's — the 120's exempt.

The shed's thresholds
The 120 sq ft (the 10x12's — the 200's; the 2026's), the 10x12 (the 120's — the 200's; the 2026's), the 200 sq ft (the 120's — the 10's; the 2026's), the 2026 (the 120's — the 10's; the 200's), the 120 (the 200's — the 10's; the 2026's), and the 10x12 (the 200's — the 120's; the 2026's).
When rules apply
The 120 (the 10x12's — the 200's; the 2026's), the 10x12 (the 120's — the 200's; the setbacks'), the 200 (the 120's — the 10's; the 2026's), the 2026 (the 90's — the 120's; the 200's), the 90% (the 2026's — the 120's; the none's), and the 120 (the 200's — the 10's; the 2026's).
Cost
The $0-$150 (the zoning's — the 2026's; the 120's), the $1,000-$6,000+ (the 120's — the 10's; the 0's — the 150's), the 120 sq ft (the 10's — the 0's — the 150's; the 200's), and the 2026 (the 120's — the 0's; the 120's). The 120's — the 10x12's shed; the 200's — the 120's exempt.
The bottom line
Tool sheds (120 sq ft/10x12 typical; 200 sq ft exempt in many codes) need building permits in only ~10% of jurisdictions in 2026 ($0-$150) — budget $1,000-$6,000+; the setback and HOA rules are the real gates.
